Network isolation method, device and system

Abstract

The invention provides a network isolation method, including the following steps: a corresponding first virtual server is accessed through a preset address corresponding to a current network of a network switcher, input login information is received, and the login information is sent to the first virtual server, so that the first virtual server generates and returns a first user session corresponding to the login information, the first user session includes a first session identifier used for identifying a user, and when the first user session is received, a first virtual machine which runs through the first virtual server runs a virtual desktop. A terminal can only be accessed to the first virtual server corresponding to the current network of the network switcher, isolation of different networks is realized, at the same time, the virtual desktop can be accessed in different networks only through one common terminal, equipment cost is reduced, and operation is simple and convenient. In addition, a network isolation device and system are also provided.

Description

technical field [0001] The invention relates to the field of network communication, in particular to a network isolation method, device and system. Background technique [0002] With the continuous improvement of network information security requirements, more and more enterprises and institutions have deployed two physically isolated networks. The internal network environment is used to access the internal office system of the enterprise, and the external network environment is used to meet external office needs. A set of network isolation system to effectively protect the internal data security of the unit. [0003] Some traditional network isolation systems use multiple hosts to access the internal and external networks separately, which has the problems of high cost, large footprint, and high power consumption. Although some use a PC system, they need to manually modify the host when switching networks. IP or a customized host with two hard disks and two network cards, ...

[0003] Some traditional network isolation systems use multiple hosts to access the internal and external networks separately, which has the problems of high cost, large footprint, and high power consumption. Although some use a PC system, they need to manually modify the host when switching networks. IP or customized host with two hard disks and two network cards, each hard disk is equipped with an operating system, and the system needs to be manually restarted every time the network is switched, the operation is cumbersome and the ease of use is low
